SUCTION CLEANER.

Application led December 4, 1922. Serial No. 604,789.

This invention relates to suction cleaners of the portable electrically operated type, comprising an electric motor and suction fan mounted in a casing adapted to be moved about a floor andhaving a suction nozzle adapted to collect the dustand litter therefrom. The objects of the invention are the provision of a' device of this character of smaller height, greater stability, fewer l0- parts, and simpler construction than heretofore; the rovision of a device ofthis character having new and improved relation ot nozzle, fan, and motor; the provision of a device of this character which can be more easily made andaof fewer parts than prior devices, while further objects and advantages of the invention will become apparent as the description proceeds.

ber and nozzle; Fig. 6 illustrates the adaptation of my improvements to al cleaner where-` in the motor is vertically mounted beneath the fan chamber; Fig. 7 is a side elevation of a machine vhaving a horizontal motor located between the fan chamber and nozzle; and Fig. 8 is an inclined plan view correspending to the line 8-78 ofFig. 5.

Describing thev parts by reference characters, 1 represents the nozzle, 2 the fan chamber, 3 the fan casing, and 4 the motor casing of my improved cleaner. The nozzle terminates at one end in a narrow elongated downwardly facing inlet mouth 5 located at its widest point, whence it. narrows rearwardly to a point substantially at the junction of the fan and motor castings., These 'casings are -spaced axially apart to definel an annular passage-way 6 which communicates on the one side with the nozzle and on the other side with the' inlet opening 7 ofthe fan casing; the lip of this inlet opening is deected into the fan casing as shown at 8 while the side of the fan casing op osite thereto is provided with a remova le In the drawings accompanying andforming a part of this application I 'have shown tion, and a bottom plan of the cleaner shown closure plate 9. Projecting froml the motor `casing toward or into the opening 7 is a through the opening to prevent strings and the like from becoming wound into the bearing. The top ofthe motor chamber is covered by a removable cap 16 and the sides of the casing are formed with bosses 17 for the rcceptionof the arms 18, 18 of the fork'which carries the handle 19. The casing is supported on thel floor inv working position by means of forward wheels 20 and a rear caster 2l. The fan chamber is formed with a peripheral outlet neck 22 to which is attached one end of the porous dust bag 23, the opposite end-.of which is supported from the handle. 'i

The casing may be arranged so that the common axis oi' the motor and fan is vertical, in which case the niotor may be above and fan below as in Figs. 1 and 3, or the fan above and motor below as in Fig. 6; or it may be mounted with this axis horizontal as in Fig. 7 or inclined as shown in Fig. 5. In any# case the entire casing can readily be cast in one piece, the opposite ends of the motor and fan chambers -only having removable closures. The device so produced is lcwerand more stable than can otherwise be produced.

In case it be desired to employ an estension hose lthe arrangement shown in Fig. 1 may be employed. A chamber 25 traversing the nozzle from side to side is closed by a cover 26 having an opening 27 adapted to receive the hose connection 28. Hinged be neath this cover is a flap door 30 adapted when elevated to close the opening 2T and when depressed to close the passage through the nozzle. It is ordinarily held elevated by the spring 31 but is depressed by the insertion of the hose connection. In case the spring 31 is reasonably strong the Jfriction of thedooi will hold the connection against accidental disconnection, but additional means can be employed if desired.

I do not restrict myself to any shape or construction of. nozzle, nor position of the arts, nor details of construction except as efned inthe annexed claims.

Having thus described my invention what I claim 1s: i 1. In a suction cleaner a casin having a vertical motor casin and a an' casing spaced apart to provi e a passageway and a nozzle communicating with said passageway, said fan casing having an axial inlet opening communicatingV with said passageway and also having a peripheral outlet neck, and a fan in said casing having a circular disk adjacent to the floor and at the side opposite said inlet opening and having a plurality ot' open vanes on the side adjacent said opening.

2. In a suction cleaner, a casing having a motor and a fan chamber having a common vertical axis, the fan chamber having .an inlet opening upon the side next to the motor, a shaft projecting from the motor into the fan chamber, a fan on said shaft having a circular imperforate disk located horizontally adjacent to the ioor at the side opposite said inlet, and a nozzle projecting from one side of the casing and communicating with said inlet opening.

3. In a suction cleaner, a casing, having a motor chamber at the top, a fan chamber at the bottpm and a passageway between WALTER A. FRANTZ.
